Now the game itself weighs over 7GB in download, and this means that if you spent yesterday downloading the game, today you will spend more time downloading its 5.5GB patch. If you have a particularly slow internet connection then it looks like you could be out a couple of hours waiting for the patch.
According to the patch notes, it seems that the fixes for the game are pretty big. For example some of the issues that were patched include, “Fixed illusions being able to manipulate and sell items”, “Fixed Huskar causing significant framerate loss”, and “Fixed a crash when dire or radiant ancients are destroyed,” just to name a few.
For those hearing about DotA 2 Reborn for the first time, basically this is Valve’s attempt at giving DotA 2 a new set of graphics. The game will now run on Valve’s Source 2 engine and will also see an overhaul of the menu system, the user interface, and other aspects of the game, some of which are no doubt welcome by players.
